, Specification forming part of Letters Patent No. 129,622, dated July16, 1872.

SPECIFICATION.

Be it known that `I, WILLIAM TELLNER, of New York city, in the county ofNew York and State of New York, have invented certain new and usefulImprovements in Mechanical Movements for Toys; and I do hereby declarethat the following is a full, clear, and exact description thereof, thatwill enable others skilled in the artto which it appertains to makeanduse the same, reference being had to the accompanying drawing and tothe letters of reference marked thereon, which form a part of thisspecification.

This invention relates to certain improvements in the propellingmechanism of toy automatons; and said mechanism is specially designedfor application to the figure of an elephant, inasmuch as the motionimparted by it to the figure closelyresembles the walk of an elephant;but of course, by slight changes, I can apply my machinery to figures ofother animals, such as cows, lions, horses, &c. The invention consistsof the following mechanism: Suppose the toy to be constructed is thefigure of an elephant, as shown in the drawing 5 ordinary clock-worksmay be used as the motive power. A shaft passing through the frame ofthe clock-works, and geared with the main or driving-wheel of saidworks, has an eccentric on each end outside of the frame, whicheccentrics revolve in bearings in the hind legs and impart to them anup-anddown motion, which is so converted, by means of slots in the upperextensions of the legs engaging with studs on the frame, as to give thelegs the necessary back-and-forth motion for progression. The motion ofthe hind legs is communicated to the front legs by rods connecting them.The head, turning on a central pivot, is given an intermittentreciprocating motion by means of connection with an arm projecting fromone of the front legs, so that there is not only the semblance of theelephant in the walk, but the head also has imparted to it a naturalmotion.

In the drawing, Figure l is a top-plan view. Fig. 2 is a side elevationof my invention as 'applied to a toy elephant. Fig. 3 is an eleva- A isa frame containing clock-work B or other suitable motive power. Thisframe, of course, will conform with the shape of the animal represented.In the rear of the frame is fixed a shaft, gearing, by means of apinion, with the main or driving wheel. On the ends of this shaft,outside of the frame, are secured eccentrically cams a a, one on eachend, which cams are xed on said shaft with their longest radiusesopposite each other. These cams or eccentrics a a find bearings in metalplates b, shaped like the legs of the animal, andforming a partthereof'. Ouryed slots c are made diagonally across the upper part ofthe legs, through which studs d pass into the frame. When motion isimparted, which may be done by winding up the spring of the clock-work,the cams will give to the legs alternately an up-and-down motion, whichis also made a back-and-forth motion by the slots and studs, so as topropel the ligure. Rods e connect the hind and front legs, and impart tosaid front legs f a backandforth motion. The legs f are pivoted to theframe, and have only the back-and-forth motion of the hind legs. A rodor arm, g, projects from the upper end of one of the front legs, andpasses through a slot in the head h of the animal. The head is securedto the frame by a central pivot, and when motion is applied to themechanism the arm g imparts to said head an intermittent reciprocalmovement on said pivot similar to the movement of the head by the liveanimal when walking. The hind feet are provided with projections i,extending inwardly, for pre-I serving the equilibrium of the toy. whilein motion. One front and one hind leg on opposite sides move together,so that the toy is supported always on at least two legs. This alternatemotion of the hind legs is attained by means of the arrangement of thecams on the shaft with their longest radiuses in opposite directions, sothat one leg is raised and the other lowered at each revolution of theshaft. Slight modifications of this mechanism will render it applicableto toys representing other animals, the machinery, of course, beinginclosed with a covering representing the animal. The mechanism can beapplied to creeping dolls by jointing the legs and the arms.
